One measure of conceptual implicit memory is repetition priming in the generation of exemplars from a semantic category, but does such priming transfer across languages? That is, do the overlapping conceptual representations for translation equivalents provide a sufficient basis for such priming? In Experiment 1 (N = 96), participants carried out a deep encoding task, and priming between languages was statistically reliable, but attenuated, relative to within-language priming. Experiment 2 (N = 96) replicated the findings of Experiment 1 and assessed the contributions of conceptual and non-conceptual processes using a levels-of-processing manipulation. Words that underwent shallow encoding exhibited within-language, but not between-language, priming. Priming in shallow conditions cannot, therefore, be explained by incidental activation of the concept. Instead, part of the within-language priming effect, even under deep-encoding conditions, is due to increased availability of language-specific lemmas or phonological word forms.The degree to which memory processes transfer between languages is an indicator of both the extent to which a memory measure relies on conceptual-level processing and the extent to which episodic representations of translation equivalents are shared across languages. The present study compares repetition priming within and between languages in an implicit memory task that has been classified as conceptually driven. Two experiments measured the extent of transfer between languages and the impact of non-conceptual processes on repetition priming in category exemplar generation.Dissociations among various implicit memory tasks have revealed that implicit memory has multiple cognitive and neural bases (see, e.g., Gabrieli, 1998). In the present investigation, instead of comparing patterns of priming for different tasks, the component processes within a single priming paradigm were isolated to reveal multiple mechanisms of priming. Implicit memory is exhibited in several behaviorally observable transfer or priming phenomena. Repetition priming can be measured as an increase in accuracy, a decrease in response time, or a response bias based on previous exposures to specific items. Several repetition priming paradigms have been developed to measure the bias to produce items presented at encoding, including category-exemplar generation, word-stem completion, word-associate generation, Corresponding Author: Wendy S.
